The Science of Environmental Pollution
by Frank R. SpellmanThis new edition of The Science of Environmental Pollution presents common-sense approaches and practical examples based on scientific principles, models, and observations, but keeps the text lively and understandable for scientists and non-scientists alike. It addresses the important questions regarding environmental pollution: What is it? What is its impact? What are the causes and how can we mitigate them? But more than this, it stimulates new ways to think about the issues and their possible solutions. This third edition has been updated throughout, and contains new information on endocrine disruptors in drinking water, contaminated sediments in surface waters, hydraulic fracturing wastewater, and more. Also, it will include new case studies, examples, and study questions. Environmental issues continue to attract attention at all levels. Some sources say that pollution is the direct cause of climate change; others deny that the possibility even exists. This text sorts through the hyperbole, providing concepts and guidelines that not only aid in understanding the issues, but equip readers with the scientific rationale required to make informed decisions.

The Science of Influencers and Superspreaders: Using Networks and Artificial Intelligence to Understand Fake News, Pandemics, Markets, and the Brain (Understanding Complex Systems)
by Hernán A. Makse Marta ZavaThis book explores the identification of influencers in complex networks, bridging theoretical approaches with practical applications across diverse fields. It examines interdisciplinary complex systems, including online social media, biological networks, brain networks, socioeconomic and financial systems, and ecosystems. The research presented aims to benefit scientists in relevant areas and inspire new scientific inquiries, potentially advancing the field of influencer identification. In this context, 'influencer' serves as an umbrella term for essential, core, or central nodes within any complex network. The book investigates various manifestations of influencers, such as key figures in social media, critical nodes in genetic and brain networks, keystone species in ecosystems, systemically important banks in financial markets, and disease superspreaders. These diverse scenarios are approached by mapping the influencer identification problem to challenges in physics or computer science. The book caters to readers at three distinct levels: 1. Those seeking mathematically rigorous theories of influencers will find Chapter 2 particularly valuable, as it delves into the mathematical foundations of influencer identification algorithms. Subsequent chapters explore the application of these theories across various disciplines. 2. Data scientists interested in implementing these algorithms in their research and practical work will find relevant information throughout the book. 3. Professionals in finance, marketing, politics, and social media, as well as readers curious about the intersection of big data, influencers, and AI, will gain insights into how these tools can enhance decision-making processes. These readers are encouraged to focus on the introduction and chapters most relevant to their fields, while briefly reviewing the more technical sections. By offering this multi-layered approach, the book aims to provide a comprehensive understanding of influencer identification in complex networks, from theoretical foundations to real-world applications across various domains.

The Science of Ocean Pollution
by Frank R. SpellmanThe marine environment supports nearly half of the universal primary production, and a great share of which drives global fisheries. The Science of Ocean Pollution is written and presented in the author’s characteristic conversational style and provides comprehensive coverage of the current situation regarding pollution in the world’s oceans. Even though our welfare is intricately linked, interconnected with the sea and its natural resources, humans have substantially altered the face of the ocean within only a few centuries. The face of today’s sea is quite apparent, obvious and visible; it floats. This book examines pollution runoff, plastics, oil spills, and other pollutants that float in our seas as well as methods to best remediate these issues.
The Science of Ocean Waves: Ripples, Tsunamis, and Stormy Seas
by J. B. ZirkerAn unparalleled introduction to the amazing world of ocean waves.Outstanding Academic Title, Choice"Powerful ocean waves fascinate the public, and they have made a lot of news lately." With that indisputable observation, scientist J. B. Zirker takes off on a whirlwind tour of the world of waves—from the "ordinary" waves that constantly churn the sea to the rogues or freaks that can rise up seemingly from nowhere to heights of 20 meters or more... and everything in between.Addressing questions most ocean visitors have had and offering new ones for our consideration, The Science of Ocean Waves explains in accessible language how waves are formed, how they move, how they become huge and destructive, and how they're being studied now for clues that will help us plan for the future.Devoting chapters to wind, tides, currents, breakers, tsunamis, forecasting, renewable energy, and El Niño—as well as discussing the gentler properties of ocean waves which inspire us and offer opportunities for relaxation and recreation—Zirker explores the physical factors that create waves.Drawing on some of the recent storms that have devastated entire regions—such as Hurricane Katrina, the tsunami launched by the 2004 Sumatran earthquake, and the great tsunami that crushed the shore of Japan in 2011—Zirker explains the forces that cause these monster waves and reveals the toll they take on human lives.Enhanced by dozens of illustrations and a comprehensive glossary, The Science of Ocean Waves will fascinate anyone curious about the science behind the headlines.Praise for J. B. Zirker"Scientists know their stuff but are rarely good storytellers, whereas good storytellers rarely possess the necessary sweeping command of a scientific discipline. Zirker is that rare animal who can both communicate the most demanding technical detail and make it accessible."—New Scientist
The Science of Open Spaces
by Charles CurtinFrom the days of the American Frontier, the term "open spaces" has evoked a vision of unspoiled landscapes stretching endlessly toward the horizon, of nature operating on its own terms without significant human interference. Ever since, government agencies, academia, and conservation organizations have promoted policies that treat large, complex systems with a one-size-fits-all mentality that fails to account for equally complex social dimensions of humans on the landscape. This is wrong, argues landscape ecologist and researcher Charles Curtin. We need a science-based approach that tells us how to think about our large landscapes and open spaces at temporally and spatially appropriate scales in a way that allows local landowners and other stakeholders a say in their futures. The Science of Open Spaces turns conventional conservation paradigms on their heads, proposing that in thinking about complex natural systems, whether the arid spaces of the southwestern United States or open seas shared by multiple nations, we must go back to "first principles"--those fundamental physical laws of the universe--and build innovative conservation from the ground up based on theory and backed up by practical experience. Curtin walks us through such foundational science concepts as thermodynamics, ecology, sociology, and resilience theory, applying them to real-world examples from years he has spent designing large-scale, place-based collaborative research programs in the United States and around the world. Compelling for not only theorists and students, but also practitioners, agency personnel, and lay readers, this book offers a thoughtful and radical departure from business-as-usual management of Earth's dwindling wide-open spaces.

The Science of Spin: How Rotational Forces Affect Everything from Your Body to Jet Engines to the Weather
by Roland EnnosA clear and captivating work of popular science that explains rotational force—a basic driver of the universe affecting everything from the cosmos to our own bodies—from the masterful author of The Age of Wood.From the time women first used rotating bobbins to twist thread and men whirled slings around their heads to throw stones, people have found spin fascinating and baffling in equal measure. Now, in The Science of Spin, Roland Ennos shows how rotational motion dominates the workings of the world around us. It has shaped the solar system, galaxies, and black holes. It controls our climate and weather—from the pattern of trade winds through to the local formation of hurricanes and tornadoes. Harnessing the power of spin helped launch civilization, from the first developments of the wheel to the systems that now power the industrial world—propellers, turbines, centrifugal pumps, and electric motors. Even our own bodies are complex systems of rotating joints and levers. But scientists have a tendency to ignore the simple and straightforward. So, 17th-century scientists developed the science of mechanics to explain the phenomenon of the orbit of the planets rather than how machines work. And Newton&’s laws have actually limited our understanding of spin because they focus on linear motion rather than on an intuitive grasp of rotation. As a result, few people realize how spin makes our planet habitable, or how it has been tamed by engineers to make our lives more comfortable. In a lively and engaging style, Ennos presents a new approach to mechanics that not only helps us better understand the world, but also reveals unlikely links between tightrope walkers and tyrannosaurs, catapults and tennis players, stunt cars and long jumpers. By opening our minds, he shows how we can all learn to move about more gracefully, play sports more successfully and safely—and ensure that, like cats, we always land on our feet. A highly entertaining and informative read, whether it be natural or engineered, spin is what really makes the world go round.

The Scoop on Poop
by Dan ChirasFlush it and forget it is the plumbing mantra of the industrialized world. Most people just want sewage to go away, preferably without having to see, smell, or worse yet, touch it. But crap has a bad rap. Human waste is a valuable resource we can use to support food production. Blackwater, greywater, and solids are actually rich in organic matter, and alternative means of handling these "wastes" can conserve enormous quantities of fresh water for other uses.The Scoop on Poop presents a wide range of ways to answer the call of nature, and in so doing to maximize the benefits of existing waste water. This book explores proven alternatives to Western sanitation. Whether you're interested in composting toilets, outdoor grey- or blackwater planters, constructed wetlands, or other innovative solutions, author Dan Chiras will walk you through: System pros and cons Design, construction, and maintenance advice Costs, permitting issues, and the safe treatment of composted wasteAll system plans are relatively simple and straightforward enough for the average homeowner to build and install. Intended for readers who live in cities, towns and rural environments, this is a practical guide to safe, ingenious ways to capture the nutrients from waste and recycle them back into your soil to grow fruit trees, vegetables, and flowers--all without running afoul of the "ick" factor. Dan Chiras is the author of over thirty books on residential renewable energy and green building, and is the director of the Evergreen Institute's Center for Renewable Energy and Green Building.
The Scope of Geography (Routledge Library Editions: Social and Cultural Geography)

The Scramble for the Amazon and the Lost Paradise of Euclides da Cunha
by Susanna B. HechtA “compelling and elegantly written” history of the fight for the Amazon basin and the work of a brilliant but overlooked Brazilian intellectual (Times Literary Supplement, UK).The fortunes of the late nineteenth century’s imperial powers depended on a single raw material—rubber—with only one source: the Amazon basin. This scenario ignited a decades-long conflict that found Britain, France, Belgium, and the United States fighting with and against the new nations of Peru, Bolivia, and Brazil for the forest’s riches. In the midst of this struggle, the Brazilian author and geographer Euclides da Cunha led a survey expedition to the farthest reaches of the river. The Scramble for the Amazon tells the story of da Cunha’s terrifying journey, the unfinished novel born from it, and the global strife that formed the backdrop for both. Haunted by his broken marriage, da Cunha trekked through a beautiful region thrown into chaos by guerrilla warfare, starving migrants, and native slavery. All the while, he worked on his masterpiece, a nationalist synthesis of geography, philosophy, biology, and journalism entitled Lost Paradise. Hoping to unveil the Amazon’s explorers, spies, natives, and brutal geopolitics, Da Cunha was killed by his wife’s lover before he could complete his epic work. once the biography of Da Cunha, a translation of his unfinished work, and a chronicle of the social, political, and environmental history of the Amazon, The Scramble for the Amazon is a work of thrilling intellectual ambition.

The Sea Floor
by Wolfgang Berger Eugen SeiboldMan's understanding of how this planet is put together and how it evolved has changed radically during the last 30 years. This great revolution in geology - now usually subsumed under the concept of Plate Tectonics - brought the realization that convection within the Earth is responsible for the origin of today's ocean basins and conti#65533; nents, and that the grand features of the Earth's surface are the product of ongoing large-scale horizontal motions. Some of these notions were put forward earlier in this century (by A. Wegener, in 1912, and by A. Holmes, in 1929), but most of the new ideas were an outgrowth of the study of the ocean floor after World War II. In its impact on the earth sciences, the plate tectonics revolution is comparable to the upheaval wrought by the ideas of Charles Darwin (1809-1882), which started the intense discussion on the evolution of the biosphere that has recently heated up again. Darwin drew his inspiration from observations on island life made during the voyage of the Beagle (1831-1836), and his work gave strong impetus to the first global oceanographic expedition, the voyage of HMS Challenger (1872- 1876). Ever since, oceanographic research has been intimately associ#65533; ated with fundamental advances in the knowledge of Earth. This should come as no surprise. After all, our planet's surface is mostly ocean.
